Quitting smoking before pregnancy could reduce infant deaths

CDC researchers examined 3.3 million births in the U.S. in 2002 and found that smoking during pregnancy could be linked to as many as 8% of premature births and 19% of full-term babies with a low birth weight that year. If the mothers had quit smoking, the researchers estimate that up to 7% of the deaths among premature infants and 34% of deaths caused by SIDS could have been prevented.
